Product Information

Freeze dried ice-cream has been aboard space missions since the early Mercury Missions, and they continue to be used on NASA missions today.

How is Astronaut Ice Cream® Freeze-Dried?

Freeze-drying, or lysophilization, removes water from the ice cream by lowering the air pressure to a point where ice shifts from a solid to a gas. The ice cream is placed in a vacuum chamber and frozen until the water crystalizes. The air pressure is lowered, creating a vacuum, forcing air out of the chamber; next heat is applied, vapourising the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a perfect freeze-dried ice cream slice.
